One of the major problems that I have with firesteels - and I speak as someone who carries one for 16 hours a day - is protecting it. The best solution that I have come up with so far is to coat it with nail varnish. Which works, but I have to recoat on a regular basis.


You might try using a bit of heat shrink tubing. Cut it a little long, shrink on, cut to remove excessive over hang. Then slide off and apply few drops of nail polish or hot glue to keep the tubing from sliding off and slide back on. It should last longer than the nail varnish while still being easily removed.
